She does not need to "dry out" to shed.
Sounds like you have mites.
Do some research, shedding does not happen in only a few days, it is a process that takes over a week from start to finish.
Snakes look like they go back to "normal" before they shed.
If she has cleared up and has not yet shed just wait a day or 2 and she will have.
Should be a one piece shed if she has been soaking that much.
*HINT* The reason she is soaking so much is because she has mites, NOT because she is shedding.
